If we decrease the amount of force and keep all other factors the same what will happen to the amount of work?
It will decrease in the same proportion.
What does work involve?
Work involves force and effort.Lifting a basket would be considered doing work. You put force on the basket and use effort to lift it. But, carrying a basket is not doing work.
What must you be doing in order to be doing work?
Moving a force through a distance.
How you can exert a large force on an without doing any work?
Work requires two items, force and motion.
Does a pulley make work easier by changing the direction of force?
Yes. It can also decrease the amount of work needed in exchange for a long distance.
How do you decrease the amount of force needed to do work?
Decrease friction.
What increases when you decrease the slant of an inclined plane?
the work output

Why carrying a bag not doing work?
carrying a bag not doing work cause without force.

Explain how machines make work easier if they do not decrease the amount of work you need to do?
A machine makes work easier by changing the amount of force you exert, the distance over which you exert your force, or the direction in which you exert your force.
What must you be doing in order to be doing work?
Moving a force through a distance.

In the force has a component in the opposite direction from the motion the work done is negative?
No the work done is still positive, the force exerted and the work done to exert that force is still the same. Its just that the other object is exerting more of a force on the object doing the work.
What type of work is being done when pushing?
1) When you push an object on a flat surface work is being done against the force of friction (and air resistance). Work is calculated by the formula: Work = Force applied x distance moved in the direction of the force 2) When you push a spring to compress it, you are doing work against its stiffness In this case, Work = Force applied x 0.5 x decrease in length of spring 3) When you push something vertically upwards, you are working against gravity Here, Work = mass x earth's gravity x height raised
